Frank Winnold Prentice MC (17 February 1889 – 19 May 1982) was a British merchant seaman and the assistant storekeeper on the ocean liner RMS Titanic during her maiden voyage.

[1] Prentice signed on to Titanic's crew on 4 April 1912 as an assistant storekeeper, having transferred from another White Star liner, Celtic.

At the time of the collision, Prentice was in his berth on the port side of E deck talking to one of the five fellow storekeepers with whom he was sharing the cabin.

Prentice however moved aft and ended up on the port side of Titanic's crowded poop deck alongside his colleagues Cyril Ricks and Michael Kieran.

The men climbed over Titanic's railing and Prentice noticed the large amount of debris and number of people floating nearby.

Very cold from the time he spent in the water, Prentice tried to drink a bottle of whisky, but it was thrown out by Quartermaster Walter Perkis, who was in charge of the boat.

When the First World War broke out in 1914, Prentice was still serving on Oceanic and was onboard when she was wrecked just ten days into her military service.

[2] Prentice continued to work at sea during the 1920s, even serving several times on Titanic's sister ship RMS Olympic.
